CVE-2024-32668

An insufficient boundary validation in the USB code could lead to an out-of-bounds write on the heap, with data controlled by the caller. A malicious, privileged software running in a guest VM can exploit the vulnerability to achieve code execution on the host in the bhyve userspace process, whic...

CVE-2024-45063

The function ctlwritebuffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing. Malicious software running in a guest VM that exposes virtioscsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process,...

CVE-2024-8178

The ctlwritebuffer and ctlreadbuffer functions allocated memory to be returned to userspace, without initializing it. Malicious software running in a guest VM that exposes virtioscsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which...

CVE-2024-42416

CVE-2024-42416 affects FreeBSD ctl(4) CAM Target Layer: ctl_report_supported_opcodes did not properly validate a field from userspace, enabling an arbitrary write into limited kernel help memory. Impact: guest VMs using virtio_scsi can abuse this to execute code on the host bhyve process (root), ...

CVE-2024-42416 Multiple issues in ctl(4) CAM Target Layer

The ctlreportsupportedopcodes function did not sufficiently validate a field provided by userspace, allowing an arbitrary write to a limited amount of kernel help memory. Malicious software running in a guest VM that exposes virtioscsi can exploit the vulnerabilities to achieve code execution on...

CVE-2024-41928

Malicious software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve...

CVE-2024-41928

FreeBSD 's bhyve hypervisor is vulnerable to a buffer overflow in the MMIO handler for the emulated TPM device . This occurs when bhyve is configured with -l tpm,passthru,/dev/tpmX, as the handler fails to properly validate the offset and size of memory access. This allows a guest VM to read or w...

FreeBSD Security Vulnerabilities

FreeBSD is a set of Unix-like operating systems from the FreeBSD Foundation. A security vulnerability exists in FreeBSD versions 13.1 and 13.2, which stems from a buffer overflow vulnerability in the fwctl driver state machine. The vulnerability can be exploited to execute arbitrary code as root ...
